PETER,CLARK, OF NEIV YORK, N. Y.

FRICTION SASH-BALANCE.

SPECIFICATION forming part of Letters Patent No. 572,049, dated November 24, 1896.

Application filed June 5, 1896. Serial No. 594,368. (No model.)

T 0 all "whom it may concern:

Be it known that 1, PETER CLARK, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Supports for Vindow-Frames, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof, in which similar letters of reference indicate corresponding parts.

This invention relates to supports for window-sashes, and the object thereof is to provide an improved device of this class whereby the sashes may be supported at any desired point without the use of counterbalance weights.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which-- Figure 1 is afront view of a portion of a window-frame and a portion of the upper and lower sashes mounted therein, part of the construction being shown in section; Fig. 2, a section on the line 2 2 of Fig. 3, and Fig. 3 a side view of the lower sash. V

In the drawings forming part of this specification I have shown at A a part of a window-frame and a part of the upper and lower sashes B and C, which are mounted therein, and in the practice of my invention I secure to the sides of the frame, adjacent to each of the sashes, an elastic metal strip D, which extends from the upper to the lower part of the frame. In the drawings forming part of this specification I have shown but one-of these strips D, but it will be understood that each of the sashes is provided at its opposite sides with one of these strips. Each of the sashes is also provided at its opposite sides with a longitudinal or vertical groove E, in whichis secured a metal plate F, having two oblong slots or openings G, by means of which a cross-piece H is formed and two end pieces K.

That part of the sides of the sashes adjacent to the cross-piece H is cut out, as shown at L in Fig. 1, and the metal strip D is passed with the usual beads M, by which the sashes are held in place and the lateral movement thereof prevented.

It is evident that changes in and modifications of the construction herein described may be made Without departing from the spirit of myinvention or sacrificing its advan tages, and I reserve the right to make all such alterations therein and modifications thereof as fairly come within the scope of the invention.

Having fully described my invention, I claim as new and desire to secure by Letters Patent- The combination with the frame of a window, and the sashes mounted therein, of metal strips secured to the frame, adjacent to the sides of each of the sashes, said sashes being provided in their sides adjacent to said strips with grooves, and with metal plates secured therein, said metal plates being provided with two oblong slots wherebya central crosspiece and two end pieces are form ed, and said metal strips being passed through said oblong slots back of the central cross-pieces, subence of the subscribing witnesses, this 2d day of June, 1896.

' PETER CLARK.
